Python convert csv to json with nested array without pandas

[terrydidi]

I'm trying to insert new array inside the array but I'm not sure where can I append the data.

Csv table

date, id, description, name, code
2016-07-01, S56202, Class A, Jacky, 300-E003

Currently, my result is

    "date": "2016-07-01",
    "id": "S56202",
    "items": [{"description": "Class A",
         "code": "300-E003",
         "name": "Jacky"},

Here is my code

    import csv
    import json
    from itertools import groupby

    with open('student.csv', 'r') as csv_ledger:
        r = csv.DictReader(csv_ledger)
        data = [dict(d) for d in r]

        groups = []

        for k, g in groupby(data, lambda r: (r['id'], r['date'])):
            groups.append({"date": k[1],
                           "id": k[0],
                           "items": [{k: v for k, v in d.items() if k not in 
                                    ['ref_num', 'date']} for d in list(g)]})

I need to insert another array in items then add the email, code and name into the new array.

Expected result

    "items": [{"description": "Class A",
               "new_account": {"email": "[email protected]",
                               "code": "300-E003",
                               "name": "Jacky"}}]
